MEANS FOR RADIATING CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 480,830, dated August16, 1892.

Application led April 28. 1892. Serial No. 430,999. (No model.)

To all whom it may concern.-

Be it known that I, HORACE REsLEY, a citizen of the United States, and aresident of Cumberland, in the county of Allegany and State of Maryland,have invented certain new and useful Improvements in Railroad-CarMounting; and I do hereby declare the followlng to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My present invention relates to railroadcar mounting,and isdesigned,priinarily, as an improvement on my patent, No4-11,976, datedDecember 2, 1890.

The rocking motion of railroad-cars, especially in rounding curves,throws the greater weight toward the inner rail, thereby lessening theweight on the outer rail and tending to make the truck jump the track.My invention aims to avoid this danger by automatically adjusting thetrucks to the rails so that their axles will be in the radial lines otthe curve, which causes the train to move easily along the track withoutthrowing the weight of the train disproportionately on either rail andpreventing the wheels of the train from impinging against the outerrail.

With these ends in view the invention contemplates a swinging postpivoted or hinged to a plate secured on the car-body above the ends ofeach upper bolster, which post operates in a countersunk portion of abearingplate secured on the upper bolster, said bearing-plate being bentupward to provide a rest for the car-body on turning a curve.

My invention further consists of the construction and arrangement ofparts, as will be hereinafter fully described and claimed.

To enable others to readily understand the invention, I have illustratedthe same in the accompanying drawings, in which- Figure l is a sideelevation. Fig. 2 is a transverse sectional view on the line a of Fig.l. Fig. 3 is a detail view showing the position of the swinging post onthe inner end of the bolster when rounding a curve. FigAf is a detailview showing the position of the swinging post on the outer end of thebolster when rounding a curve.

Refer-rin g to the drawings, in which like letters of reference denotecorresponding parts in all the figures, A designates the bottom of thecar-body, and B B the trucks, which are pivotally connected to thecar-body by kingbolts a. The lower bolster b is connected with thecross-piece Z9 on the truck by pins or bolts C, and suitable coiled orelliptical springs c are interposed between the lower bolster and thecross-piece on the bolts C or other bolts to provide a yielding bed forthe car. At the outer end of each lower bolster, on the upper sidethereof, is a bearing-plate D, which is partially or Wholly countersunk,as desired, and is constructed and bent to form a depressed seat CZ anda shoulder d in front of said seat. y This plate is rigidly secured tothe bolster in a suitable manner, and by countersinking the same it ismore eitectually held fromV displacement. preferably made of one pieceof metal; but this is not essential, and it may be constructed ot two ormore pieces and solid at cl', if desired. Above these plates, on theouter end of each upper bolster E, is a plate e, which is countersunk,preferably, and provided with an upwardly-extending offset or shouldere, which affords a firm hold upon the bolster and prevents a backwardstrain, and displacement of the plate. A swinging post or spar F ispivoted or hinged to the plate e at one end, and it extends downward andrests in the seat d of each bearing-plate on the lower bolster. It willbe observed that these swinging posts are pivoted on opposite ends ofthe plates e on the same side of lthecar and on the same ends of saidplates on the opposite ends of the holsters for a purpose hereinafterdescribed. 'lhese plates e and swinging posts F are preferably made ofstrong metal, as they are designed to partially sustain the weight ofthe car and are subjected to the various uneven and unusual movements ofthe car, which they are designed to obviate.

The operation of my improvements may be stated as follows: Vhen the caris traveling along a straight track, the swinging posts will be inclinedat a slight angle to the body of the car and fitted in the seats d ofthe bearing-plates, the swinging posts on the same The bearing-plate isIOO side of the car being inclined reversely toward each other and theshoulders d being on opposite sides of said posts. When the car isrounding a curve, the outer rail being always higher than the inner railthe outer edge of the car-body and outer sides of the trucks approacheach other, which is also largely due to centrifugal action; but theswinging posts on the inner sideof thecar-body will assume a verticalposition and maintain the carin its properlevel. As the car reaches andbegins the curve, the increased pressure on the outer side of the carforces the swinging posts in the direction in which they are inclinedreverselyto each other, andthis forces the outer ends of the front truckforward and the corresponding end of the rear truck backward. Thisposition of the trucks will thus bring the axles thereof into diagonalpositions with reference to each other and the axes of the Wheels intothe radial lines of the curve, which adapts the truck to move easily andsmoothly around the curve without unduly impinging against the rails. Atthe same time the inner ends of the trucks will move toward each other,and the swinging posts will thus be forced into a vertical position andelevate the inner side of the carbody, keeping the car-body in a levelposition.

To relieve the swinging posts of as much strain and weight as possible,the shoulders d are provided,and the outer side of the car may restpartially upon said shoulders as the curve is being rounded. When thecurve is rounded, the devices will automatically return to theiroriginal positions.

My improvements may be adapted to all kinds of railway-cars,locomotive-trucks, and to other cars or vehicles.

I am aware that changes in the form and proportion of parts and detailsof construction of my invention may be made without departing from thespirit or sacrificing the advantages thereof, and I therefore reservethe right to make such changes as fairly fall within the scope of thesame.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with the trucks of a car and the body mountedthereon, of the swinging posts hinged to the car-body and arranged tobear against the truck-bolster and adjust the trucks to a curve of thetrack, substantially as described.

2. The combination, with the trucks of a car and the body mountedthereon, of the bearing-plates on the lower bolster and the swingingposts hinged at one end to the carbody and adapted to bear at their freeends against said plates, substantially as and for the purposedescribed.

3. The combination, with the trucks of a car and the body mountedthereon, of the bearing-plates secured on the lower bolsters and havingdepressed seats and the posts depending from the body and fitted 1n saidseats and adapted when rounding a curve to adjust the trucks so that theaxles thereof will be in the radial lines of the curve, substantially asdescribed.

4. The combination, with theutrucks of a car and the body mountedthereon, of the swinging posts pivotally secured to the carbody or upperbolsters and the bearngplates on the lower bolsters, having seats torecelve the free ends of said posts, substantially as and for thepurpose described.

5. The combination, with `the trucks of a car and the body mountedthereon, of the swinging posts pivotally hung from the upper bolstersand the bearing-plates secured on the lower bolsters beneath said postsand having seats to receive the free ends of the posts and also providedwith the shoulders to sustain the car-body, substantially as described.

G. rlhe combination, with the trucks of a car and the body mountedthereon, of the lower bolsters on the trucks and the upper bolsters onthe body of the car, the bearingplates secured on the lower bolsters,and the shoulders on said plates to receive the weight of the car,substantially as described.

7. The combination, with the trucks of a car and its body mountedthereon, ot' the bearing-plates secured on the lower bolsters and havingdepressed seats therein, the plates secured to the upper bolsters, andthe swinging posts pivoted or hinged to said plates and having theirfree ends fitted in said seats in the bearing-plates, substantially asdescribed.

In testimony whereof Iax my signature in presence of two Witnesses.
